Be it known that I, LOUIS AUGUSTE FAVRE, of Geneva,'Switzerland, have invented a new or improved Device for Securing the outer Sole or Pattern and the Heel to Boots or Shoes; and I do hereby declare that the f ollowingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make ariduse the same, reference beinglxad to the accompanying plate of drawings, forming part of this specification.

This invention consists in securing to the under side 'of the inner sole, whether it is sewed or nailed to-the vamp, a metallic plate, which-is provided with smallperforations or slots, and-in securing said plate, either by nails, rivets, screws, or other suitable means, thereon.V The outer sole or pattern, which is to be connected to the-sole, and to completel the shoe, is provided with a set of` projecting screws or tenons on its upper face, said screws or tenons being intended to t into corresponding slots in the plate. These slots are either tapering or in the form of a bayonet-joint, s o that, if the pins of the pattern fare fitted through the broader parts ofthe slots, and if then the pattern is moved sideways on the sole, the tenons shall fit into the narrow portions of the slots in such manner that thesaid pattern is thus secured to the sole, andcannot be taken o the shoe, unless it is made to slide back as far as it was moved on, or, in otherwords, unless, by a sliding motion of th'e pattern,

all the small projectibns or 'tenons are `freed at once from their respective or corresponding slots. These slots are cut of a tapering or bayonet-joint form, with inclined or recessed edges; but, by preference, the cutshould be mode of angular shape, so as to prevent the outer sole from accidentally sliding oithe shoe while in the act ofpwalkingf The applying and removing of the pattern are, in that case, e`ectedV by a. double slidin'gmotion, Y

the first4 motion being in a direction which is at about a right angle to the next one. Further, the tenons or projecting parts are aiixed to the pattern and the slots formed in the inner sole, as shown; but the positions of `these two parts may be inverted; that is to say,the slots may be fitted in the outersole or pattern', and the projectingparts in the inner sole. p

This mode of securing the pattern to the sole is-very plain, substantiah'and cheap. The new soling may he made again and again hy anyperson unskilled i'n shoe-making, as the seam, nailing, or screwing whereby the vamp is secured to the sole remains untouched. In the annexed drawing- Figure 1 represents a side view` of a shoe provided with an outer sole or pattern, set or axed a.ccdr-' ding 4 to my system. y

Figure 2 shows an inverted plan view of the same, theipattern or outer solo being removed. Figure shows a detached plan view of the pattern.- Y Figure 4` shows partly a sole formed with appropriate grooves for obtaining a bayonetjoint. Similar letters of reference indicate corresponding parts. p i a represents a common or ordinaryfshoe. b is the. inner sole, on which is to be tted the outer sole or pattern e, (iig. 3.) d is a metallic frame or plate, axed lto the inner sc le by means of screws, e, or otherwise. i 'This metallic frame is formed with any desired number of tapering or other holes or slots, f, which are narrowerA at onerend than at the'other, as shown. gg are tenons or small'projections secured on the pattern c, in nunber equal to that 'of the slots on the frame.- They are so formed as to enter the said slots, and slide thereon, so as to securely connect the pattern or outer sole to the shoe.

Between the inner and outer sole may he interposed any cork, Indiafrubber, or other gnmmy, water-proof, or elastic sole, either oiled or not. This thus interpolated sole 'may be so cut out aslto occupy or cover the whole surface of the inner sole, in which case it should be perforated with holes for admitting the small tenons,

4or only thesurfacel comprised within the frame. The shoe-heel may, in like manner, be securedV or xed to the s ole, as shown in-fig. 2.

It is evident that this invention is applicable to all kinds of boots and shoes. I claim as new, and desire to secure by Letters Patent- The metallic plate d, rigidly secured to the inner sole b, and provided with slots, f, adapted to receive and retain projections g, on the cuter sole c, as and for the purpose set forth.'
